Already used Prodiamine however keep getting some bittercress and henbit popping up. I talked to a local service in the neighborhood and he said they also use Simazine as well. Would this be a good tactic? Could I mix the 2 if so?
Princep Liquid Herbicide can be tank mixed with Prodiamine 65 WDG for a more broad spectrum pre emergent application provided a Compatibility Test is ensure they are physically compatible. With Prodiamine 65 WDG being a wettable dispersable granule, we recommend mixing it in first allowing it to dissolve first before adding the liquid pre-emergent and/or using an agitator in your tank. Princep and Prodiamine are labeled for henbit however do not list hairy bittercress as a weed it will control. Gallery herbicide would be a better option as the active ingredient isoxaben is labeled for both hair bittercress and henbit. Also, late summer/fall pre emergent applications are going to provide better results than early spring pre emegent applications. Please view the Gallery product label for more information.
